These characteristics make it ideal for heavy duty applications that demand long term STTH810G-TR STTH810G reliability. STTH810FP STTH810FP Such demanding applications include industrial STTH810DI STTH810DI power supplies, motor control, and similar mission-critical systems that require rectification and freewheeling. These diodes also fit into auxiliary functions such as snubber, bootstrap, and demagnetization applications. The improved performance in low leakage current, and therefore thermal runaway guard band, is an immediate competitive advantage for this device.
